Celebrating his dad! Oliver Hudson made headlines earlier this week for slamming his biological father, Bill Hudson, via Instagram in a post that read, “Happy abandonment day…. @katehudson.” But on Wednesday, June 24, he had a much kinder message for the man who raised him, Kurt Russell.

Bill, the biological dad of both Oliver and his younger sister, Kate Hudson, divorced the pair’s mother, Goldie Hawn, in 1980. Several years later, Hawn, now 69, began dating Russell, now 64, and the two Hudson kids consider him to be their real dad.
